It wont be so easy, I'm afraid. Even if comunication issues are solved, you won't be able to copy your ROM using windows file manager, opening the phone like a conventional drive...
You have to install "ADB" in your PC (search in HTC ONE subforums, there's a lot of info about ADB pusing (=copying) ROMS) and use it to copy your ROM. One advice: while "pushing" the ROM, be patient: it takes a long time. When your ROM is "pushed", just install it in recovery and... that's it!!
I think here
you have a good starting point.
